Since DD was a couple of months old she has normally gone around 3-4 days between poos and I think the longest stretch was 6 days after which we had a bit of an explosion!
She seems very happy and is smiling and playing just the same as usual so clearly not distressed or uncomfortable; think I read somewhere that it is only a cause for concern if BF babies get to 10 days without a poo but I am sure someone out there will know if that is right or not.
Am thinking of calling in Dynorod if she hasn't gone by tomorrow morning!!!
